As a higher education institution in New York State, we are bound by regulations that require us to protect personally identifiable information (PII) for our students. (I'm sure this is true of many, if not all, states in the USA, and many other nations, as well.) Machform provides some challenges in this regard, because of its great dependence on email. For example, the only way to send a copy of the data submitted to the form back to the person submitting it, to serve as a receipt, is to email it. But email (as is quite well known) is an inherently insecure means of communication, so we cannot use this method.
I would like to see a new feature added to Machform which would allow a form to send a confirmation email to the person who filled out the form, which contains, instead of the submitted data placed in the body of the email or into a PDF attached to the email, a link that would allow the person who received the email to view (but not edit) their information securely within their browser and, optionally, download a PDF file containing the submitted information. This link would expire after a period of time that could be set by the person who created the form (or edited it later). It would have to be possible to regenerate this link so it could be sent to people who needed another copy of their receipt or who didn't take advantage of their first opportunity to download it.
While this wouldn't be completely secure, since anyone who intercepted the email and followed the link before it expired could still see the submitted information, I think it would be acceptable secure for most purposes.
Obviously, my requested feature has many points in common with the new feature that allows users to edit and re-submit their previously submitted data, but it would have to be a completely separate feature which generated a separate link with an independent time limit.
It seems to me that the code for the new "edit entries" feature could be leveraged to create the new feature I am requesting without too much trouble. (Of course, it easy for me to say that, since I don't have to do the work.)
